    The User Profile Service failed the logon. User profile cannot be loaded.

    How to Fix the Error "The User Profile Service failed the logon. User profile cannot be loaded."

    information   Information
    When you log on to Vista or Windows 7 using a temporary profile (user account), you receive this error message:

    The User Profile Service failed the logon. User profile cannot be loaded.

    For more information, see:
    Error message when you log on to a Windows Vista-based or Windows 7-based computer by using a temporary profile: "The User Profile Service failed the logon. User profile cannot be loaded"
    Note   Note
    CAUSE:

    The jury is still out on the exact cause, but so far :
    • This issue may occur if the user profile was manually deleted by using the command prompt or Windows Explorer by a user or by some program. A profile that is manually deleted does not remove the security identifier (SID) from the user profile list in the registry. Since the SID is still present, Vista will still try to load the profile by using the ProfileImagePath that points to a nonexistent path. Therefore, the profile cannot be loaded.
    • This can also be a issue with the user profile entering into a backup state.
    • Manually renaming the C:\Users\(User Name) user profile folder.

    If you have this error message below instead, then see: How to Fix the Error "Your user profile was not loaded correctly! You have been logged on with a temporary profile." in Vista

    Your user profile was not loaded correctly! You have been logged on with a temporary profile.

    Changes you make to this profile will be lost when you log off. Please see the event log for details or contact your administrator.

    Tip   Tip
    If the steps in the tutorial below do not help or you wish to try this first, then:





    STEP ONE

    Log on to the Computer
    warning   Warning
    You must be logged on to an administrator account using either step 1 or 2 below before you can move on to do either the OPTION ONE or OPTION TWO sections.
    1. To Log on to another Administrator account.
    NOTE: If you do not have another Administrator account, then proceed to step 2.
    A) Go to OPTION ONE or OPTION TWO.
    OR

    2. To Boot into Safe Mode and Use the built-in Administrator account
    NOTE: You may not need to enable the built-in Administrator account. If this was the only normal administrator account you had, then Safe Mode should automatically boot into the built-in Administrator account.
    Tip   Tip
    If you cannot boot into Windows and do not have a Windows installation DVD, then you can create and use the boot disc below to boot into Safe Mode with instead.

    How to Create a Windows 7 System Repair Disc

    Vista: (Option One at link)
    How to Create a Vista Recovery Disc

    A) Boot into Safe Mode (in Vista) or Safe Mode (in Windows 7).

    B) If Safe Mode did not boot into the built-in Administrator account, then enable the built-in Administrator account. If it did, then go to step 2D.

    C) Log off in Safe Mode, and then log on to the built-in Administrator account to logon with that account in Safe Mode.

    D) Go to OPTION ONE or OPTION TWO.



    OPTION ONE

    To Fix the User Account Profile
    1. Open the Start menu.

    2. In the white line (Start Search) area, type regedit and press Enter.

    3. If prompted by UAC, either click on Continue (Vista) or Yes (Windows 7).

    4. In regedit, go to: (See screenshot below step 5)
    Code:
    HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList
    5. In the left pane, look for the S-1-5..... folder (SID key) with the long number that has .bak at the end of the numbers.
    (See screenshots below steps 6A and 7B)
    NOTE:
    A) In the right pane, look at the ProfileImagePath to verify that this is the user account profile that has the error.
    B) You may have another S-1-5..... folder (SID key) above it with the exact same number without the .bak at the end of it.

    6. If you have Two S-1-5..... folders (SID key) with the same Number
    NOTE: This is if you have two S-1-5..... folders (SID key) with the exact same numbers, but the second (below) one has the .bak at the end of the numbers.
    A) In the left pane, right click on the first (top) S-1-5..... folder (SID key) that does not have .bak at the end of the numbers and click Rename. (See screenshot below)

    C) In the left pane, right click on the second S-1-5..... folder (SID key) with .bak at the end of the numbers and click Rename. (See screenshot above)

    D) Remove only .bak from the end of the numbers and press Enter. (See screenshot below)

    E) Now go back and Rename the first one with .bk to .bak now at the end of the numbers and press Enter.
    The User Profile Service failed the logon. User profile cannot be loaded.-repar_bak.jpg
    F) Go to step 8.
    7. If you have Only One S-1-5..... Folder (SID key) with .bak
    NOTE: This is if you only have one S-1-5..... folder (SID key) for your user account with .bak at the end of the numbers.
    A) In the left pane, right click on the S-1-5..... folder (SID key) with .bak at the end of the numbers and click Rename. (See screenshot below)

    B) Remove only .bak at the end of the numbers and press Enter. (See screenshot below and below step 10)
    The User Profile Service failed the logon. User profile cannot be loaded.-repair_reg2.jpg
    8. In the right pane of the one without .bak now, right click on RefCount and click on Modify. (See screenshot below step 10)
    NOTE: If you do not have RefCount, then right click on a empty space in the right pane and click New and DWORD (32 bit) Value, then type RefCount and press Enter. This value for this entry will reset and return back to the original value after you have restarted the computer and logged on to the account.
    A) Type 0 (number) and click on OK. (See screenshot below)

    11. Close regedit.

    12. Restart the computer.

    13. See if you can logon now.
    NOTE: If this still does not help, then either try OPTION TWO below or see the yellow TIP box at the top of the tutorial.



    OPTION TWO

    To Delete the User Account and Create Another One

    warning   Warning
    You can do this option if you do not care about losing the user account and the contents in the user folders. Your programs will still be installed, but you will need to create new shortcuts for them afterwards.
    1. Delete the User account profile that this error is for.

    2. Open the Start menu.

    3. In the white line (Start Search) area, type regedit and press Enter.

    4. If prompted by UAC, click on Continue (Vista) or Yes (Windows 7).

    5. In regedit, go to: (See screenshot below step 7)
    Code:
    HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList
    6. In the left pane, click on one of the S-1-5..... folders (SID key) with the long number in it.
    NOTE: It may have .bak at the end of it.
    A) In the right pane, look at the ProfileImagePath to see if this is the same user account that you deleted in step 1 above.

    B) Repeat step 6 until you find the one that you deleted in step 1 above.
    NOTE: If the user account is not here, then it has already been removed when deleted in step 1. Go to step 9.
    7. To Backup the Registry SID Key
    WARNING: You should backup this SID key to be safe in case you delete the wrong one in step 8 below.
    A) Right click on the SID key, and click on Export.

    B) Type in a name and save the REG file to a safe location.
    NOTE: This is your backup. To Restore the Backup, right click on the REG backup file and click on Merge.

    C) Continue on to step 8.
    The User Profile Service failed the logon. User profile cannot be loaded.-sid_reg.jpg
    8. To Delete the Registry SID Key
    A) Right click on the SID key, and click on Delete. (See screenshot above)

    B) Click on Yes to confirm deletion. (See screenshot below)

    9. Close regedit.

    10. Now, just create a new normal Administrator account.

    That's it,

    Hi badgrrrl,

    Welcome to Vista Forums.

    Sorry to hear that, but System Restore is a good option to. Unfortunately, the exact cause has not been narrowed down yet, just how to fix the resulting problem. The Cause at the top of the tutorial may help some, but if you noticed anything that you may have installed or changed before it happened to you it may help narrow it down more.

    Hi tanuj chadha,

    Try taking ownership of the SID registry key with the BAK on it first, then see if you can rename it to remove BAK. OPTION TWO step 3 will show you how to do this here:

    Take Ownership of file

    I have tried everything on the list. All I get is error message, stating that I cannot rename.
    I also do not have anything in the right field. It's blank!

    Hi bigvern,

    Welcome to Vista Forums.

    If the right side is empty, then that user profile (account) is history. While you are in the built-in Administrator account, see if you can create another normal Administrator account and logon to it. If you can, then delete the old account. If not, then I'm afraid it is time to do a reinstall.

    bigvern,

    If you have a Upgrade Vista installation DVD:
    How to Do a Clean Install of Vista with a Upgrade Version


    If you have a Full or OEM Recovery Vista installation DVD:
    How to Do a Clean Install with a Full Version of Vista


    If you only have a Recovery partition, then restart the computer and press F10 or F12 (usually) every second until a Recovery Manager screen comes up. There will be an option to reinstall Vista there. You will need to check your OEM computers documents for their (EX: Dell, HP, etc...) exact procedure, but it should be similar.

    Hope this helps,
    Shawn
